SIPHON-PUMP SPECIFICATION forming part of Letters Patent No. 503,232,dated August 15, 1893.

Application led February 23, 1893. Serial No. 463,391- (No model.) Y vT0 all whom it may concern:

Be it known that I, EDWARD A. FRANKLIN, a citizen of the United States,residing at Austin,in the county of Travis and State of Texas, haveinvented a new and useful Siphon-Pump for Oil-Cans and Transfer of otherLiquids, of which the following is a specification.

The invention relates to improvements in siphons.

The object of the present invention is to provide a simple andinexpensive siphon for transferring liquid from one receptacle intoanother adapted to be readily applied to the ordinary oil can, andcapable of enabling a liquid to be transferred from a reservoir to areceptacle without liability of spilling any of the liquid and ofreturning the latter to the reservoir when desired. v

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a sectional view of a siphon constructed inaccordance with this invention and applied to a can, the rubber sectionor leg of the Siphon being shown in full lines in position for filling alamp, and in dotted lines in an elevated position for emptying a lampand transferring the contents back to the can. Fig. 2 is a detailperspective view of the lower head of the cylinder. Fig. 3 is a reverseplan view of the same.

Like numerals of reference indicate corresponding parts in all thefigures of the drawlngs.

1 designates a metallic tube forming the short leg of a siphon andhaving its upper end connected detachably with a flexible leg 2 ofrubber or other suitable material, adapted to have its lower endreadilyconstricted by squeezing with the fingers to enable it to be readilytransferred from one lamp or othervessel to another, and adapted to beelevated, as illustrated in dotted lines in Fig. 1 of the ac-Icompanying drawings to transfer the contents or a portion of thecontents, in case a lamp is.

filled too full, back to the reservoir or can 3. The upper end of therigid metallic tube or pipe 1 is curved outward, and is secured belowthe curved portion to a screw cap 4 of the oil can. The lower end of therigid tube 1 is secured to and communicates with a short cylinder 5,which is considerably shorter than the tube 1 and is adapted to bearranged in the oil can considerably below the top or cap to avoid anyliability of the liquid being forced out of the can at the screw capthrough leakage by the upstroke of a piston rod 6, as would be the casewere the pump cylinder the same length as the tube 1 and terminated atthe screw-cap. The top of the cylinder is connected with the screw capby a brace 7 and is arranged close to and parallel with the tube 1,whereby the vcombined diameter of the cylinder and the tube may bereadily made less than the diameter of the ordinary oil can screw-cap,in order that the siphon may be readily applied to any ordinary oil canand inserted through its opening.

The piston-rod 6 extends through a perforation of the screw-cap,terminates at its upper end in a handle and is provided at its` lowerend with a piston 8,wliich when raised creates a vacuuml in lower end ofcylinder 5. This vacuum immediately fills with liquid from thereceptacle through the valve opening 11. The downward stroke of thepiston 8 closes the valve 12 and liquid is forced through the opening inthe cylinder, into the lower end of the tube`1, One stroke of the pistonwill in most cases start the flow of liquid through the siphon, afterwhich the ow will be continuous without the use of the pump as will bereadily understood.

The oil or other liquid enters the cylinder through a valve which opensinwardly, and a'perforation 9 which-*relieves the pressure on the valveand which when the flexible leg of the siphon is raised above the oilcan permits the oil to iiow back into the can. The lower cylinder headhas an annular flange 10, which is secured to the body of the cylinder,and it is provided with a valve opening 11 and has secured to its upperface a flexible disk 12 of leather, which forms with the opening 11 thevalve. The flexible valve disk 12 is secured to the cylinder head bytongues 13 formed integral with the cylinder head and bent downward onthe upper face of the disk 12, the latter closing the openings formed bycutting the metal to provide the tongues.

roo

It will be seen that the siphon is simple and comparatively inexpensivein construct-ion and is adapted to be readily applied to the ordinaryoil can, and that it is capable of readily transferring a liquid fromone receptacle to another and back again. It will also be apparent thatin filling lamps, should too great a supply of oil be transferred to alamp, a por tion may be readily returned to the receptacle.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrilieingany of the advantages of this invention.

What I claim isl. The combination with a receptacle, of a siphon havinga rigid leg arranged in the receptacle and an outer iiexible leg, acylinder shorter than the rigid leg of the Siphon and located below thetop, a screw-cap secured to the rigid leg of the si phon near the upperend thereof,a brace having its upper end secured to the screw cap andits lower end fastened to the cylinder, a piston rod passing through thescrew cap and extending into the cylinder, and a piston secured to thepiston rod, substantially as described.

2. The combination with a Siphon, of a pump having its cylindercommunicating with the siphon and provided in its lower cylinder headwith a valve opening and having integral tongues, and a iiexible valvedisk arranged over the valve opening and secured beneath the tongues,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

EDWARD A. FRANKLIN.
